Thank you for your feedback!! The music is actually royalty free, I forgot to include our credits list on the details page, check out Kevin Macleod for TONS of awesome music.
We had some scheduling changes as a team and got done what we could, but upgrading weapons and more visual cues will definitely be on the essential systems list next time. I appreciate your feedback on the melee weapon--I didn't think to consider a visual hitbox for the sword!
